DARPA is exploring the potential of growing large-scale biological structures (500+ meters) in microgravity, leveraging recent advances in metabolic engineering and biological self-assembly. The initiative aims to revolutionize space infrastructure by enabling the biological manufacturing of structures like space elevator tethers, orbital debris nets, and space station components.
